Return Error Execution

This example shows how to configure output to have only certain kinds of errors returned while others thrown.

import { Graffle } from './graffle/__.js'

const pokemon = Graffle
  .create({
    output: {
      envelope: false,
      errors: {
        execution: `return`,
        other: `throw`,
      },
    },
  })

// 1. The __execution__ error of an empty Pokemon name will be ***returned***.

type _result = typeof result
const result = await pokemon.mutation.addPokemon({
  $: { name: ``, hp: 1, defense: 0, attack: 0, $type: `water` },
  name: true,
})
console.log(result)

// 2. The __other__ error, in this case from the inline extension, will be ***thrown***.

try {
  await pokemon
    .anyware(({ encode: _ }) => {
      throw new Error(`Something went wrong.`)
    })
    .query
    .pokemons({ name: true })
} catch (error) {
  console.log(error)
}
